FIG. 1 is a conceptual diagram showing a system according to an embodiment of the present invention.

Referring to FIG. 1 , a system 100 according to an embodiment of the present invention may include multiple machines 101, 102, 105, and 106, and a relation server 104.

In FIG. 1 , for the convenience of description, a user 103 is shown together with the above components, and may be a user or a user terminal.

Although four machines 101, 102, 105, and 106 are illustrated in FIG. 1 by way of example, the technical scope of the present invention should not be construed as being limited to any specific number of machines included in the system 100.

Each of multiple machines 101, 102, 105, and 106 may have its own machine profile.

The machine profile means data including various types of information related to each machine 101, 102, 105, or 106. According to an embodiment, the machine profile may include at least one of the parameters of the machine profile presented in the following Table 1. Each of the machine profile parameters may include at least one sub-parameter.

In the present specification, the term “sub-parameter” may denote a parameter including detailed items for the corresponding parameter.

TABLE 1 Parameters of machine profile Sub-parameters Status Current operation (active) state Current availability or unavailability (standby) Current process Scheduled termination time of current process Currently executed function Scheduled termination time of currently executed function Capability Title of process Input parameter Output parameter Process processing time Process processing condition(s) Function 1 Function 2 . . . Function n Machine ID — User ID — Group ID — Machine Operating system type operating system Operating system version Machine interface Interface protocol(s) between machines Interface parameter(s) between machines Interface protocol(s) between machines and relation server Interface parameter(s) between machines and relation server

The currently executed function may denote the function that is currently being executed among various functions that are executed in order to perform a single process. For example, the currently executed function may be a function such as ‘washing’, ‘rinsing’, or ‘spin-drying’, performed for the process ‘laundering’.

The sub-parameters of the capability parameter may include the title of a process, which can be processed by each of the machines 201, 202, 204, and 205, an input parameter, an output parameter, a process processing time, a process processing condition, and multiple functions related to the executable task (function 1, function 2, function 3, . . . , function n). The input parameter may refer to information that is input in order to operate the corresponding machine, and the output parameter may refer to information that is output from the corresponding machine depending on the results of operation.

The machine ID parameter denotes a unique identifier allocated to each of the machines 101, 102, 105, and 106 to identify each of the machines 101, 102, 105, and 106.

The user ID parameter denotes a unique identifier allocated to a user who is capable of utilizing each of the machines 101, 102, 105, and 106.

The group ID parameter denotes a unique identifier allocated to a user group (e.g. members of a family, members of a specific company, etc.) that is capable of utilizing each of the machines 101, 102, 105, and 106.

The sub-parameters of the machine operating system (OS) parameter may include the type and version of the OS that is used by each of the machines 101, 102, 105, and 106.

The sub-parameters of the machine interface parameter may include interface protocols between the machines 101, 102, 105, and 106, interface parameters between the machines 101, 102, 105, and 106, interface protocols between each machine 101, 102, 105, or 106 and the relation server 104, and interface parameters between each machine 101, 102, 105, or 106 and the relation server 104.

In accordance with an embodiment, the machine profile may be defined and implemented in the form of a schema having a hierarchical structure. That is, the machine profile may be defined and implemented as a data structure having a structure system such as that given in Table 1. In this case, the machine profile may further include a tag, indicating the last portion of each parameter (or machine profile), in the last portion of each parameter (or the last portion of the machine profile).

The system 100 of FIG. 1 is a centralized system in which the machines 101, 102, 105, and 106 are grouped by the relation server 104 and the sequence of the operations of the machines 101, 102, 105, and 106 is designated.

The relation server 104 may perform a grouping for the machines that have been previously registered in the relation server 104 or that are extractable (that is, capable of being selected) by a communication with the relation server 104 among various machines.

The relation server 104 may generate a capability set required to execute a command by analyzing the command input from the user 103, and may group the machines 101, 102, 105, and 106 based on the generated capability set and the machine profiles of the machines 101, 102, 105, and 106, for example, capability parameters and status parameters.

In the present specification, the term ‘analysis of a command’ may be used interchangeably with the term ‘analysis of a task corresponding to a command’.

According to an embodiment, the relation server 104 may form relations between the machines 101, 102, 105, and 106, based on the capability set, the capability parameters and the status parameters of the respective machines 101, 102, 105, and 106, and generate a relation profile based on the relations. The generated relation profile may be stored in the relation server 104 or a storage space associated with the relation server 104.

The term ‘relation’ in the present specification may mean a concept including not only machines (i.e. a machine group) associated to collaborate with each other on a process, but also a task processing schedule (e.g. the sequence of operations, a task collaborative relation, etc.) required to allow the machines to perform the process.

According to an embodiment, the present invention may further include a procedure in which the relation server 104 analyzes the command using the data prestored in the relation server 104 or in the storage space associated with the relation server 104 when the relation profile is generated. In this case, the relation server 104 may form the relations between the machines 101, 102, 105, and 106 based on the analyzed command and the capability parameters and the status parameters of the respective machines 101, 102, 105, and 106 and may generate a relation profile based on the relations.

According to an embodiment, the relation server 104 may request an intervention of a user to the user 103 according to the processes included in the relation profile. The intervention of the user may include an approval or a selection of the user related to an execution of the processes. In this case, the user 103 may transmit a result of the approval for all of the processes or the selection for a part of the processes to the relation server 104, by responding to the request from the relation server 104. The said user intervention step may be performed at various times according to an embodiment. For example, the intervention of the user may be performed after the relation profile is generated or be performed before an addition work is conducted.

According to another embodiment, the relation server 140 may request the intervention of the user to the user 103 only when a process result of the processes included in the relation profile make a critical effect on the user 103.

The relation server 104 may re-group the machines 101, 102, 105, and 106 according to the intervention (e.g. the approval of the selection) of the user 103, and may generate a new relations of the re-grouped machines. And, the relation server 104 may generate a new relation profile according to the new relations.

According to an embodiment, relation profile may include at least one of the parameters presented in the following Table 2. Each of the parameters of the relation profile may include at least one sub-parameter.

The term “task” in the present specification may mean a set of processes (or functions) that need to be performed based on the results of analyzing the command input from the user 103. And, the term “relation profile” in the present specification may broadly mean data representing relations formed to perform a task.

TABLE 2 Parameters of relation profile Sub-parameters Capability set Capability 1 . . . Capability n Grouped machines Machine ID 1 . . . Machine ID n Work group ID — Task description — Task processing schedule Process 1 Process start time Process start condition(s) Allocated machine ID Start time of function 1 Function 1 . . .

Process n Process start time Process start condition(s) Allocated machine ID Start time of function 1 function 1 . . . Start time of function n Function n Predicted termination time of process n Interface parameters Termination condition(s) of process n

Referring to Table 2, the parameters of the relation profile may include a capability set parameter, grouped machine parameters, a work group ID parameter, a task description parameter, a task processing schedule parameter, etc.

The capability set parameter may include information about capability parameters, which are required for relevant task, and machines may be grouped based on the capability set parameters.

The grouped machine parameters may include information about the machine IDs (machine ID 1, . . . , machine ID n) of machines grouped to perform the relevant task.

The work group ID parameter may denote the ID required to identify the entire group of the grouped machines.

The task description parameter may include various types of additional information related to the relevant task. For example, the task description parameter may include details about the tasks for the relevant task in the form of text.

The task processing schedule parameter may include relations (e.g. a processing sequence) between multiple processes (process 1, . . . , process n) and sub-parameters related to the respective processes (process 1, . . . , process n).

According to an embodiment, the sub-parameters of the task processing schedule parameter may include the process start time of each process, the start condition(s) of each process, the machine IDs of machines allocated, the functions used, the start time of each of the functions, the predicted termination time of the process, interface parameters, the termination condition(s) of the process, etc.

According to an embodiment, the relation profile may be defined and implemented in the form of a schema having a hierarchical structure. That is, the relation profile may be defined and implemented as a data structure having a structure system, such as that given in Table 2. In this case, the relation profile may further include a tag, indicating the last portion of each parameter (or the relation profile), in the last portion of each parameter (or the last portion of the relation profile).

In the present specification, the term “capability set” may be used as a concept having a level which is equivalent to the task. For example, work, that is, a capability set corresponding to a task, such as “housework” may be composed of processes (or functions) such as “cleaning”, “doing the dishes”, and “doing the laundry”.

According to an embodiment, the relation server 104 may list the machine ID parameters of the respective machines 101, 102, 105, and 106 grouped to execute the command and arrange the listed machine ID parameters according to the sequence of operations suitable for the execution of the command.

In this case, in the arrangement corresponding to the operation sequence, the status parameters of respective machines 101, 102, 105, and 106 may be taken into consideration. For example, when a relevant machine is found to be currently in an active state using the sub-parameters of the machine 101, 102, 105, or 106, the sequence of operations may be arranged in consideration of available times using the scheduled termination time parameter for the current active state.

For example, when a relevant machine is found to be currently in an available state using the sub-parameter indicating current availability or unavailability (standby state), among the sub-parameters of the machine 101, 102, 105, or 106, the operations of the machines may be arranged according to the sequence most suitable for the execution of the command.

According to the determined operation sequence, the relation server 104 may execute the command received from the user 103 by requesting each of the machines 101, 102, 105, and 106 to perform process.

In the system 100 of FIG. 1 , the machines 101, 102, 105, and 106 may be entirely controlled by the relation server 104, and thus the machines 101, 102, 105, and 106 do not need to exchange data with each other.

The relation server 104 is not limited as to the location or form thereof as long as it is capable of communicating with the machines 101, 102, 105, and 106. For example, the relation server 104 may be implemented using a smart phone.

The machine profiles of the machines 101, 102, 105, and 106 may be previously registered in the relation server 104 and may be transmitted to the relation server 104 at the request of the relation server 104. According to an embodiment, when the machine profiles are previously registered, the relation server 104 may fixedly store the capability parameters, machine ID parameters, user ID parameters, group ID parameters, machine operating system (OS) parameters, and machine interface parameters, and may update the status parameters while communicating with the machines 101, 102, 105, and 106.

The relation server 104 may always be maintained in the state in which it is capable of communicating with the machines 101, 102, 105, and 106 by setting interface protocols and protocol parameters to be used to communicate with the machines 101, 102, 105, and 106 using the machine profiles.

The method for operating the relation server 104 will be described in greater detail with reference to the scenario of FIG. 2 .

FIG. 2 illustrates an embodiment of a scenario that can be applied to the system of FIG. 1 .

Referring to FIGS. 1 and 2 , it is assumed that, in FIG. 2 , the first machine 101 is a movie search engine, the second machine 102 is a smart phone, the third machine 105 is a machine having a movie reservation function (e.g. a communication terminal in which a movie reservation application is installed), and the fourth machine 105 is a boiler control machine having a communication function.

The second machine 102 may receive a command, for example, a ‘movie recommendation’ command, from the user 103 at step S10. According to an embodiment, the command may be received via email, a social network service (SNS), or a messenger.

The second machine 102 may forward the command received from the user 103 to the relation server 104 at step S12.

The relation server 104 may analyze the received command at step S14, and may generate a capability set required to execute the command based on the results of the analysis and group the machines 101, 102, 105, and 106, which will execute the command, based on the generated capability set, at step S16. For example, the relation server 104 may group the machines that may perform processes or functions included in the capability set required to execute the command, based on the machine profiles of the respective machines 101, 102, 105, and 106.

The relation server 104 may form relations between the machines 101, 102, 105, and 106 based on the capability parameters and the status parameters of the respective grouped machines 101, 102, 105, and 106 at step S18.

According to an embodiment, the relation server 104 may utilize machine profiles in which the capability parameters and the status parameters of the machines 101, 102, 105, and 106, which have been previously registered in the relation server 104, are included.

According to another embodiment, the relation server 104 may also use machine profiles acquired from a query that is transmitted from the relation server 104 to each of the machines 101, 102, 105, and 106.

The relation server 104 may generate a relation profile based on the relations formed between the machines 101, 102, 105, and 106 at step S20.

The relation server 104 may perform management so that the machines 101, 102, 105, and 106 perform required operations at required times depending on the relation profile.

For example, the relation server 104 may set the sequence of operations of the machines 101, 102, 105, and 106 based on the machine profiles (capability parameters, status parameters, etc.) of the respective machines 101, 102, 105, and 106, and may then arrange the machine IDs according to the set sequence and store the arranged machine IDs in the relation profile.

The relation server 104 may request the first machine 101 to search for movies using the stored relation profile at step S22.

In this case, the relation server 104 may request the first machine to search for movies based on information about movies that meet movie search conditions input by the user 103 (e.g. a movie title, a movie theater, a synopsis, a running time, or the like). According to an embodiment, the movie search conditions may be included in the command input from the user 103 at step S10.

The first machine 101 may transmit the found movie information to the user 103 via the relation server 104 and the second machine 102 at steps S24, S26, and S28.

The user 103 enters information about the determination to make a reservation (e.g. the selected movie, the selected movie theater, the movie start time, the number of tickets to be reserved, etc.) in response to the found movie information, and may deliver the information about the determination to make a reservation (reservation determination information) to the relation server 104 via the second machine 102 at steps S30 and S32.

The relation server 104 may transmit a reservation request to the third machine 105 based on the received reservation determination information at step S34.

The third machine 105 may reserve a movie corresponding to the reservation determination information, and may transmit a payment confirmation request to the user 103 via the relation server 104 and the second machine 102 at steps S36, S38, and S40.

The user 103 may transmit payment confirmation to the third machine 105 via the second machine 102 and the relation server 104 at steps S42, S44, and S46.

The third machine 105 may reserve the movie in response to payment confirmation from the user 103, and may provide notification of the results of the reservation to the user 103 via the relation server 104 and the second machine 102 at steps S48, S50, and S52.

The relation server 104 may transmit a request, which is required in order to obtain the selection or approval of work that can be additionally performed in compliance with the command of the user 103 transmitted at step S10, to the user 103 at step S54.

According to an embodiment, the relation server 104 may transmit information about a list of additional works, information about machines for processing the additional works, and information about the sequence (or schedule), in which the additional works are to be processed, to the user 103.

The user 103 may select and input additional works to be conducted, and may transmit a command for selecting the input additional works to the relation server 104 at step S56.

The relation server 104 may analyze the additional work selection command transmitted from the user 103 at step S58, generate a capability set required to execute the command based on the results of the analysis, and re-group the machines 101, 102, 105, and 106, which will collaborate in the performance of the additional works selected by the user 103, based on the generated capability set, at step S60.

The relation server 104 may form new relations between the machines 101, 102, 105, and 106 based on the capability parameters and the status parameters of the respective re-grouped machines 101, 102, 105, and 106 at step S62.

The relation server 104 may generate a new relation profile based on the newly formed relations at step S64.

Thereafter, the relation server 104 may perform management so that the corresponding machines perform required operations at required times based on the newly generated relation profile.

For example, the relation server 104 may schedule the operation of a boiler so that the boiler is driven via the fourth machine 106 in accordance with the time at which the movie is to be terminated based on movie reservation information at step S66.

According to an embodiment, after the execution of the command has been completed, the relation server 104 may release the formed relations and delete the relation profile.
